I have an old manuscript that is scanned as 4 pages per A4, I need to slice it down to 4 separate pages, each page as a single file. I used actions in Photoshop to separate every two A4 into two files, a top and bottom ones with 2 pages in each of them. Now, since the scan is not very accurate, I need to manually slice these images (the ones I get from my previous step) into two separate pages, and to save time I decided to use the slice tool to slice each image into two slices, then export them for web so I get two separate image files in a single step.
The problem is that the manuscript is written in Arabic, so the direction is from right to left. Photoshop, by default, recognizes slice that starts from the very top left corner as slice #1, and other slices as #2 and/or #3. According to this order of slices the exported files will take their names, and due to that I will have page no. 2 as no. 1, and page no. 2 as no.1!
I tried to change the point of origin of the ruler, but with no luck!
How can I make Photoshop flip the document direction so it considers the top right corner as the beginning instead of the top left corner? Or is there any way to change the order of slices?
